The specific embodiment
We illustrate an embodiment of the self-traveling scavenging machine system relevant with the present invention to Fig. 8 with Fig. 1.Self-traveling scavenging machine system has the scavenging machine 1 of automatic walking and cleaning dust and the charging device 200 of powering to the battery 22 that this scavenging machine 1 has.Fig. 1 represents the sectional view of self-traveling scavenging machine 1.Fig. 1 (a) is the top figure of the A-A sectional view of Fig. 1 (b), and Fig. 1 (b) is a longitudinal section.The direct of travel of scavenging machine 1 be Fig. 1 left to.
The profile of self-traveling scavenging machine 1 is by last face shield 27 and side cover 23 circular that form.On the two sides, bottom, pair of driving wheels 4a, the 4b of walking usefulness is installed in the inside of scavenging machine 1.Can drive this driving wheel 4a, 4b respectively with the motor 2a, the 2b that are installed on the substrate.The reductor 5 that the input that makes motor 2a, 2b is slowed down is installed on motor 2a, the 2b.
About encoder 3a, 3b are installed on the rotary shaft end of walking with motor 2a, 2b.Encoder 3a, 3b will walk and output to the controller 6 of the top, rear portion that is installed in the scavenging machine 1 with the velocity of rotation of motor 2a, 2b.Controller 6 is controlled the voltage that is added on walking motor 2a, the 2b respectively.The velocity of rotation of the detected walking of controller 6 FEEDBACK CONTROL encoder 3a, 3b motor 2a, 2b, the velocity of rotation of control driving wheel 4a, 4b.
When the control direct of travel, rotate in identical direction with identical velocity of rotation by making a pair of motor 2a, 2b, make scavenging machine 1 straightaway, perhaps, motor 2a, 2b are rotated in opposite direction with identical velocity of rotation, scavenging machine 1 original place is rotated.
Joint pin 8a, 8b support reductor 5a, 5b that they can freely be rotated around the trunnion axis with the direct of travel quadrature.Reductor 5a, 5b are connected with the top of scavenging machine 1 by suspension body 7a, 7b.When reductor 5a, 5b rotated around joint pin 8a, 8b, driving wheel 4a, 4b were roughly changing the position in the above-below direction.When being placed on scavenging machine 1 on the floor, because the deadweight of scavenging machine 1 makes the spring of suspension body 7a, 7b be compressed to the shortest.Driving wheel 4b and reductor 5b are positioned on the position (α) shown in the solid line of Fig. 1 (b).When upwards lifting scavenging machine 1, the elongation of the spring of suspension body 7a, 7b makes reductor 5a, 5b and driving wheel 4a, 4b change the position on the position (β) shown in the dotted line of Fig. 1 of maximum (b).Therefore, even if the ground relief of self-traveling scavenging machine 1 walking, also can be certain make driving wheel 4a, 4b ground connection.
At scavenging machine 1 direct of travel rear side, be installed with can about change the section port body 30 of position.We illustrate the appearance of the change position of this section port body 30 with Fig. 2.Shown in Fig. 2 (a), when work, section port body 30 is contained in the inside of scavenging machine 1 usually.In this state, the profile of self-traveling scavenging machine 1 is roughly cylindrical shape.Because the profile of scavenging machine 1 is a cylindrical shape, so, then can in the place that not hindered by barrier, rotate if scavenging machine 1 does not contact with barrier.So can direction be transformed into any direction.
In addition, the profile of self-traveling scavenging machine 1 is not limited to cylindrical shape, also can be have hemispherical, the shape of the circle of the taper shape of decaptitating etc.In these shapes, in the place that not hindered by barrier, also can carry out in order to change the rotation of direct of travel.
When section port body 30 was positioned at the inside of scavenging machine 1, section port body 30 did not arrive wall etc.At this moment, shown in Fig. 2 (b), in the movable range of section port body 30, make the front end of section port body 30 outstanding from the outside of the right-hand member (line γ) of scavenging machine 1.Therefore, the front end of section port body 30 reaches wall.
Middle body at self-traveling scavenging machine 1 is carrying the battery 22 of powering to each unit.Battery 22 is Ni-MH batteries.The testing circuit that is had by controller 6 detects the voltage of battery 22.Controller 6 monitors detected voltage output, grasps charge capacity one by one.Charging terminal 14 is installed on the front side surface of scavenging machine 1.When on charging terminal 14, adding the voltage of regulation, the battery 22 of scavenging machine 1 inside is charged.
Cover 27 is installed on the top of scavenging machine 1.The details of this cover 27 as shown in Figure 3.Fig. 3 is the top figure of scavenging machine 1, and the upside of figure is a direct of travel, at the rear side of direct of travel, be installed with have a plurality of switches 15,15 ... guidance panel 46.This switch 15 is used to send power connection/disconnection, instructs to the manual control of self-traveling scavenging machine 1.On guidance panel 46, the indicator 47 of light emitting diode is installed also.The surplus of indicator 47 expression power connection/disconnections and battery 22.Also can be with LCD as indicator 47.
Cover in the above on 27 near guidance panel, infra-red remote control receiving element 16 is installed.Receive from the signal that is arranged on unillustrated infra-red remote control transmitter 100 among the outside figure with this receiving element 16.According to the signal that receiving element 16 receives, scavenging machine 1 is advanced or retreat, rotate, start/to stop the control of dust fan.Again, beginning or interruption self-discipline cleaning works.
At the peripheral part of scavenging machine 1, dispose columnar side cover 23.The top of side cover 23 is crooked to the inside, forms the joint unit with last face shield 27 in its end.In the inside of side cover 23 near side cover 23, configuration infrared distance measuring sensor 10a~10c.Infrared distance measuring sensor 10a~10c measures the distance of the object that is positioned at this sensor 10a~10c front.Output by controller 6 monitoring sensor 10a~10c.With the opposed part of light receiving unit of the infrared distance measuring sensor 10a~10c of side cover 23 be to see through ultrared material.Therefore, controller 6 can be familiar with the distance between self-traveling scavenging machine 1 and the peripheral object.
Unillustrated turn-sensitive device among the figure is installed in the inside of scavenging machine 1.Turn-sensitive device will output to controller 6 around the angular speed of the vertical direction axle of self-traveling scavenging machine.Therefore, even if driving wheel 4a, 4b slide, also can detect the angular speed of self-traveling scavenging machine 1 on the floor.
In the both sides, front side, difference of height sensor 12a, 12b are installed downwards in the bottom of scavenging machine 1.This difference of height sensor 12a, 12b are reflection type infrared distance measuring sensors, and the output expression has or not the information of the object in the light receiving unit predetermined distance range of only leaving sensor 12a, 12b.Therefore, also can detect this and subside even if the ground of the direct of travel of self-traveling scavenging machine 1 faces down to subside.If scavenging machine 1 sensor 12a or 12b in walking detect difference of height, scavenging machine 1 is stopped.And, make scavenging machine 1 conversion direction to the direction that does not have difference of height.Therefore, avoid scavenging machine 1 to turn over because of difference of height.As difference of height sensor 12, except infrared ray sensor, also can use ultrasonic sensor and contact-making switch.
Below we describe the dust collecting structure of scavenging machine 1 inside in detail.With the movable section port body of left and right directions 30 in abutting connection with disposal box 21 is set.As shown in Figure 2, in section port body 30, on the face that joins with disposal box 21, have hole 70.In disposal box 21, also on the face that joins with section port body 30, have hole 71.The air that comprises dust that sucks from section port body 30 flows by the hole of leaving section port body 30 and the disposal box 21 70,71.
Around the hole 71 of disposal box 21, liner 36 is installed.Liner 36 is used to make between section port body 30 and the disposal box 21 and keeps airtight.Liner 36 is become smooth with the Surface Machining of section port body 30 joining parts.
On substrate 45, control of dust fan 20 is installed.Disposal box 21 is remained on the downside of substrate 45.Control of dust fan 20 is connected with disposal box 21 by substrate.In the linkage unit of the disposal box 21 of substrate 45 and control of dust fan 20, have the hole of the ventilation usefulness that sucks air.In the state that disposal box 21 is installed on the scavenging machine 1, unillustrated liner keeps the air-tightness of stream among the figure.
In the face of in the part of control of dust fan 20, the filter 54 of nonwoven is installed at disposal box 21.Owing to the pressure differential that 20 work of control of dust fan produce, attract to comprise the air of dust from section port body 30.The air that comprises dust reaches control of dust fan 20 from section port body 30 by disposal box 21.And, by dust-collecting filter 54 dirt separations and air, the dust of separating is stored in the inside of disposal box 21.
Section port body 30 forms wind path because on section port body 30 and disposal box 21, have hole 70,71 respectively, so can simultaneously with about sliding simultaneously on the liner on the disposal box 21 36 change position (please refer to Fig. 2).Therefore, do not need flexible pipe and conduit, can make the scavenging machine miniaturization.Compare with the situation that makes disposal box 21 and section port body 30 integrated change positions, can make the lightweight of shift in position position, can reduce to be used to change the power of section port body 30 positions.As a result, can make left and right directions move the drive unit miniaturization of section port body 30.Section port body 30 can change the scope of position, shown in Fig. 2 (b), be when making section port body 30 the most outstanding, the hole 70 of section port body 30 does not exceed the scope of the scope of being surrounded by liner 36, and is the scope that the left end of section port body 30 does not exceed the left end of liner 36.
Transverse movement by unillustrated guide rail restriction disposal box 21 among the figure that is installed on the substrate 45.But, can in direction forward, slide along guide rail.Therefore, can take out disposal box 21 from scavenging machine 1.Disposal box 21 is given as security the position that liner 36 and the section port body 30 up to the rear end that is arranged on disposal box 21 joins in the self-traveling scavenging machine 1, the hook 28 that is arranged in the disposal box is entrenched in the hollow 29 of scavenging machine 1 one sides formation.Therefore, can limit the motion of disposal box 21 at direct of travel.
Hook 28 is elastomers, and when firmly disposal box 21 being pulled to the place ahead, hook 28 is recessed to downside.And, make hook 28 chimeric with hollow 29 disengagings of scavenging machine 1 one sides, can easily take out disposal box 21 from scavenging machine 1.Can take out the loam cake of disposal box 21 from disposal box 21.Therefore, if take out disposal box 21, then abandon the dust that is stored in the disposal box 21 easily.Again,, expose the sliding surface of disposal box 21 and section port body 30, so clean sliding surface easily because can take out disposal box.
In order to change section port body 30 positions, has the supporting arm 42 that section port body transmits motor 32, is installed in the encoder 34 on this motor 32, the snap bolt 37, the section port body initial point sense switch 90 that are connected with the axle of motor 32 and suspends support section port body 30 from the top in midair at left and right directions.
Section port body 30 is connected with snap bolt 37 by supporting arm 42.Snap bolt 37 is supported by the bearing 35 that roughly firmly keeps at the holding components 45a that is installed on the substrate 45.The linkage unit that supporting arm 42 and snap bolt 37 are coupled together is pad 43 (こ ま), is screwed into nut in inner face one side.When snap bolt 37 rotates, section port body 30 and pad 43, supporting arm 42 moves at transverse direction.
Encoder 34 detects the location variation of pad 43, and outputs to controller 6.If pad 43 is in the reservation scope then pad 43 is connected dispose section port body initial point sense switch 90 like that.And when pad 43 is outside the reservation scope, disconnect.This on/off switching position is fixed on the initial point.When the output valve with section port body initial point sense switch 90 detected initial points and encoder 34 combines, can know the position absolute value of supporting arm 42.Determine the initial point of position in the present embodiment with mechanical means, but also can use optical pickocff, this is self-evident.
The slider 33 that can change the position at transverse direction is installed at supporting arm 42 midway.In order to make slider 33 get back to neutral position, slider 33 has spring 33b.When the power of effect transverse direction on section port body 30, correspondingly change the position of slider with the size of this power.When making motor 32 rotation, section port body 30 one sides and disposal box 21 between the one side of sliding change the position at transverse direction.
If according to present embodiment, then because the front end of section port body 30 is supported arm 42 by slider 33 to be supported, so can make the front end of section port body 30 reach wall etc. always.When the exterior object of the front end of outstanding section port body 30 and wall etc. contact, can prevent owing to the counter-force from object makes self-traveling scavenging machine 1 change direction again.If the intensity of the spring of slider 33 fully a little less than, even if then the front end of Tu Chu section port body 30 contacts with object, also can prevent to damage section port body 30 and contact object.
Near the outstanding part of self-traveling scavenging machine 1, attaching contact-detection sensor 44 at section port body 30.Contact-detection sensor 44 is the sensors that dispose a plurality of switches onboard.When contacting with barrier etc., press switch with wall.Contact-detection sensor 44 outputs to controller 6 with contact position.Therefore, can detect the protuberance of section port body 30 and contacting of wall and barrier etc.
Below we illustrate the work of the self-traveling scavenging machine 1 of such formation.Self-traveling scavenging machine 1 has 2 class walking modes of self-discipline walking mode and manual walking mode.In the self-discipline walking mode, according to the information of carrying the various sensors on self-traveling scavenging machine 1 walking of restraining oneself.In manual walking mode, advance, retreat or the single work of rotation etc. according to the signal that sends from remote-controlled transmitter 100.
When starting self-traveling scavenging machine 1, it is set in the manual walking mode.In manual walking mode, the user indicates the direction of travel of scavenging machines 1 with remote-controlled transmitter 100.So if be set in the manual walking mode, the user does not pick up scavenging machine 1, make scavenging machine 1 change the position up to the room that will clean, then can alleviate the burden on user's muscle power.When working in manual mode, the switch from the guidance panel 46 of remote-controlled transmitter 100 or scavenging machine 1 sends indication to scavenging machine 1, and self-traveling scavenging machine 1 moves in the self-discipline walking mode.In the self-discipline walking mode,,, do not miss the whole room of cleaning, ground, angle, corner, limit and walk with the output of the various sensors of infrared distance measuring sensor 10a~10c etc. according to the algorithm that is stored in advance in the controller 6.
When with the self-traveling scavenging machine 1 of present embodiment record, when the self-discipline walking, can near wall and barrier, clean.Therefore, when self-traveling scavenging machine 1 cleaning wall, self-traveling scavenging machine 1 is walked along wall.When wall is walked, make and keep predetermined interval between self-traveling scavenging machine 1 and the wall surface.When making section port body 30 the most outstanding, this predetermined interval at section port body 30 with below the wall contact distance.
Ask that infrared distance measuring sensor 10a measures to poor with as the distance of target of the distance of wall.When the difference of 2 distances is timing, indication self-traveling scavenging machine 1 is near wall.When the difference of 2 distances when negative, indication self-traveling scavenging machine 1 leaves wall.Make section port body 30 outstanding, the front end that detects the section port body protuberance up to contact-detection sensor 44 is with till wall contacts.Perhaps, according to the detected distance of infrared distance measuring sensor 10a from self-traveling scavenging machine 1 to wall, the overhang of decision section port body 30.If according to a kind of method in back,, the front end of section port body 30 is not contacted with wall, near wall, clean if adjust the overhang of section port body 30.
If according to present embodiment, even if then just in case barrier is run in the front of the section port body of giving prominence to when walking 30, because contact-detection sensor 44 can detect barrier, so, also can proceed cleaning by avoiding obstacles by temporarily the suction inlet unit being contained in the self-traveling scavenging machine 1.
When cleaning during wall, often need make 1 rotation of self-traveling scavenging machine in the corner in room etc.Expression makes the appearance of self-traveling scavenging machine 1 rotation among Fig. 4.When self-traveling scavenging machine 1 in the self-discipline walking mode arrived the corner in room in the wall walking, infrared distance measuring sensor 10a, 10b detected wall.Therefore, self-traveling scavenging machine 1 one side is cleaned the corner and is simultaneously transferred to the work of rotating at this place.At this moment, if control the overhang of section port body 30 for the front end edge wall change position of section port body 30, then can reduce the not purging zone in corner.
With same when wall changes the position usually, according to the information of contact-detection sensor 44 or according to the overhang of the detected range information decision section port body 30 of infrared distance measuring sensor 10a from self-traveling scavenging machine 1 to wall.Because infrared distance measuring sensor 10a in the rotation direction (the inverse clock rotation direction of Fig. 4) of self-traveling scavenging machine 1 than the front end of section port body 30 in advance, so can be in the front end of section port body 30 shape by preceding grasp wall angle portion.Therefore, can be consistent with the shape in bight, section port body 30 is controlled at do not contact and as far as possible on the position near wall with wall etc.Even if wall constitutes with easy lost material, can not damage wall yet.In addition, when the overhang of front end of decision section port body 30, corner shape that can enough supposition room is the program of the corner shape at right angle etc.At this moment, the control of scavenging machine 1 has become simply.
On side cover 23, at the part formation otch of outstanding section port body 30.Because this otch, section port body 30 can change the position sleekly.In order to take out disposal box 21, be provided with in the bottom of the leading flank of side cover 23 and slide up and down the hole 26 of opening.
On near the substrate 45 the inner peripheral surface of side cover 23, roughly equally spaced 4 spring 25a~25d are installed.Spring 25a~25d is a piano wire, in length direction flexible hardly, but changes the position easily at bending direction.And, when removing loading, return to original state.25a~25d is configured in vertical direction with spring.The partial cross section figure of Fig. 5 has represented the details of spring 25a~25d.Cover in the above and be formed on the inboard step 27a that descends in 27 the upper end.Step 27a prevents that side cover 23 from changing the position at downside.Because this step 27a, even if downward masterpiece is used on the side cover 23, last face shield 27 also can hold on this power, avoids spring 25a~25d buckling.
In addition, because the step 27a of last face shield 27, the possible location variation of the horizontal direction of side cover 23 is limited in about 3mm.Further, because spring 25a~25d is out of shape hardly for extending force, so even if pick up the side cover 23 of self-traveling scavenging machine 1, side cover 23 can not break away from from substrate 45 yet.
Switch 24a~the 24d of the change in location of the horizontal direction of detection side face shield 23 is configured in the small gap with side cover 23.Switch 24a~24d is remained on the support 72a~72d front end that vertically is arranged on substrate 45.When changing the position in side cover 23 any one direction in the horizontal direction, 1 or 2 switch 24a~24d contacts with side cover 23, and switch 24a~24d works.Whether work according to certain switch 24a~24d, can know the roughly direction of object.The output signal of switch 24a~24d is outputed to controller 6.So if the contacts side surfaces of object and scavenging machine 1, side cover 23 changes positions, then can detect and the contacting of object.
If according to present embodiment,, at interval 4 contact-type switches are set with 90 degree roughly, so, also do not have the dead angle of detection even if contact with object in certain position because support side cover 23 one-piece type flexibly as full week by spring.Again, the required parts of testing agency seldom, it is simple and cheap that structure becomes.Because these are detected required component configuration near the side of scavenging machine 1 cover 23, so can guarantee to be used for the space of other parts at the middle body of self-traveling scavenging machine 1.Support side cover 23 because use face shield 27, so form for the strong structure of the external force of above-below direction.Because can know the roughly direction of object, take avoidance behavior easily.
In addition, as long as, just can easily change detection sensitivity by changing the rigidity of spring 25a~25d.If the movable range of the horizontal direction of side cover 23 then can be changed in the gap of face shield 27 and side cover 23 horizontal direction in the change.By the suitably rigidity of cluster spring 25a~25d and the movable range of horizontal direction, the contact detection that also can carry out soft contact.By this setting, can prevent that self-traveling scavenging machine 1 from contacting with peripheral object and damage mutually.
In order to support the side cover, use 4 switch 24a~24d for the detection position changes, but this number is being not limited to 4 in the present embodiment with 4 spring 25a~25d.The bar number of spring 25 also can be different with the number of switch 24.This switch is not limited to have the shape of the circle of using in the foregoing description, also can be the shape that has circular polyhedron etc. in the bight.In which kind of situation, also can not produce the dead angle of detection.
Unillustrated pressure sensor among the figure is installed in section port body 30.The detected pressure of pressure sensor is outputed to controller 6.Exist and in the process of using self-traveling scavenging machine 1, take place to be attracted mouth 40, can not attract the situation of the state of affairs of dust by obstructions such as paper.At this moment, section port body 30 pressure inside sharply descend.When continuing this state for a long time, the motor 20a that drives control of dust fan 20 becomes overload state, and self-traveling scavenging machine 1 breaks down.Therefore, detect section port body 30 pressure inside, avoid the overload state of motor 20a by pressure sensor.
Specifically, sharply descend, then temporarily stop the attraction of scavenging machine 1 if pressure sensor 13 detects pressure.Section port body 30 pressure inside become and equal atmospheric pressure when stopping to attract, and take out easily attached to attracting object in the mouth 40.Secondly, by only making scavenging machine 1 walking preset distance, also can take out attached to attracting object in the mouth 40.Begin once more to attract to confirm that pressure returns to state just often, begin cleaning once more.When pressure differential does not return to just often state, repeat above-mentionedly to stop to attract and scavenging machine 1 is walked.Even if when repeating this formality pre-determined number normal pressure can not be got back to, stop to attract to end cleaning.In order to allow the user know the generation abnormal conditions, indicator 47 demonstrates error message.
Along with store dust in disposal box 21, at suction condition, section port body 30 pressure inside descend and diminish.Because pressure sensor monitors the pressure when control of dust fan 20 is worked, so can detect the dust storage case in the disposal box 21.Indicator 47 is expressed this dust storage case to the user.Store situation because can detect dust, so can know the timing of taking out dust automatically from disposal box 21.
Because scavenging machine 1 with battery 22 as power source, so need carry out charging work.Again, because the capacity of disposal box 21 also has limit, so, then need to take out dust from disposal box 21 if accumulated the dust of scheduled volume.In the present embodiment, these work are implemented on scavenging machine self-discipline ground.We illustrate this appearance with Fig. 6 to Fig. 8.
Fig. 6 is the ideograph of the charging device 200 in a self-traveling scavenging machine 1 and a corner that is arranged on the room, and Fig. 6 (a) is its top figure, and Fig. 6 (b) is its side view.Charging device 200 has lower plate portions 201 and sidewall sections 202, cassette portion 203 and charging device leader 204.Fig. 7 is the details drawing of charging device leader, and Fig. 7 (a) is its top figure, and Fig. 7 (b) is its side view.Fig. 7 (c) is the A-A sectional view of Fig. 7 (a).
Cassette portion 203 is arranged on the power supply unit of building one side.Leader 204 is connected with cassette portion 203, can be connected sleekly with the contact of scavenging machine 1 one sides when scavenging machine 1 is charged.On the end face of leader 204 1 sides of cassette portion 203, charging terminal 205 is set.Charging terminal 205 is electrically connected with charging circuit 230 in being arranged on cassette portion 203.Source power supply is supplied with charging circuit 230.
Charging device control of dust fan 206, charging device disposal box 207 and charging device controller 250 are set on cassette portion 203.The disposal box 21 of the control of dust Capacity Ratio self-traveling scavenging machine 1 of charging device disposal box 207 is big.Charging device controller 250 monitors and control charging circuit 230 flows through the electric current and the voltage of charging terminal 205, and controls the work of charging device control of dust fan 206.
On charging device leader 204, be formed with guide rail 208 that transverse width narrows down along with advancing to front end and the trapezoidal suction port 209 that is surrounded by this guide rail 208.Upper rim at guide rail 208 forms flange 208A.The top top height of suction port 209 than guide rail 208.Suction port 209 is by being communicated with charging device disposal box 207 at the inner suction passage 210 that forms of guide rail.
When 206 work of charging device control of dust fan, suck air from suction port 209.And, be included in and suck the filter 207a that airborne dust is maintained in the charging device disposal box 207 and separate, be stored in the charging device disposal box 207.Therefore, the dust that is stored in the disposal box 21 of scavenging machine 1 changes the disposal box 207 of position to charging device 200 1 sides.
Fig. 8 represents the detailed situation of disposal box 21 parts of the self-traveling scavenging machine 1 that the leader 204 of charging device shown in Figure 7 200 engages.Fig. 8 is the following figure of self-traveling scavenging machine 1, and Fig. 8 (a) is the state of closing the following baffle plate 59 that is arranged on disposal box 21, and Fig. 8 (b) is the state of opening.
Form dust-exhausting port 60 on the bottom surface of disposal box 21, baffle plate 59 covers this dust-exhausting port 60.Baffle plate 59 slides at the direct of travel of self-traveling scavenging machine 1.Spring 61 is remained on the rear portion of disposal box 21, and this spring 61 gives as security baffle plate 59 to left.When scavenging machine 1 was worked usually, dust-exhausting port 60 was covered by baffle plate 59, can not spill the dust (please refer to Fig. 8 (a)) in the disposal box 21.
When giving as security baffle plate 59 to the right, spring 61 compressions are revealed dust-exhausting port 60 shown in Fig. 8 (b).In the leading edge portion of baffle plate 59, form reclinate bending unit 62.When self-traveling scavenging machine 1 engaged with charging device 200, the lower end of bending unit 62 is than the top height of charging device guide rail 208, and was lower than the edge of suction port 209.Both sides of the chest at dust-exhausting port 58 are provided with guide rail 63.Guide rail 63 has the chimeric relation of negative and positive with the guide rail 208 of charging device 200.When self-traveling scavenging machine 1 engages with charging device 200, make the height of the height of guide rail 63 and guide rail 208 that the height of each guide rail 63,208 as one man is set.When guide rail 208 engages with guide rail 63,, the charging terminal 14 that makes scavenging machine 1 sets each charging terminal 14,205 for contacting with charging terminal 205 again.
Below we illustrate the dust discharge work of the self-traveling scavenging machine 1 of such formation with Fig. 6 and Fig. 8.The sidewall sections 202 that makes charging device 200 in advance and the wall in room ground connection mutually are provided with.If the voltage of battery 22 drops to predetermined value in the work of self-traveling scavenging machine 1, then controller 6 judges that battery allowance is few.And move to charging work.
If move to charging work, then self-traveling scavenging machine 1 directly advances to survey the wall in room forward.If controller 6 covers the output of the contact-detection sensor 44 of switch 24a~24d or section port body 30 from the side, judge to arrive wall, it is such then to make wall be in the right side of scavenging machine 1, and scavenging machine 1 is walked along wall.Continuation is walked along wall, if reach charging device 200, then climbs up lower plate portions 201 along the sidewall sections 202 of charging device 200.
When along these sidewall sections 202 walkings, make 1 of scavenging machine leave sidewall and advance according to the distance of the distance decision of guide rail 208 and sidewall sections 202.Therefore, when self-traveling scavenging machine 1 is climbed up the lower plate portions 201 of charging device 200, the guide rail 63 of the guide rail 208 of charging device 200 1 sides and self-traveling scavenging machine 1 one sides roughly over against.
When self-traveling scavenging machine 1 continued along sidewall sections 202 walkings, the front end of the guide rail 63 of self-traveling scavenging machine 1 one sides was automatically chimeric with the front end of the guide rail 208 of charging device 200 1 sides.And final 2 guide rails 208,63 connect closely.At this moment, the charging terminal 14 of self-traveling scavenging machine 1 one sides contacts with the charging terminal 205 of charging device 200 1 sides, begins energising, and battery 22 is charged.
When self-traveling scavenging machine 1 continued along sidewall sections 202 walkings, the baffle plate 59 of self-traveling scavenging machine 1 hung over the edge of the suction port 209 of charging device 200.Then baffle plate 59 is given as security and is opened baffle plate 59 to leader 204, make suction port 209 and dust-exhausting port 58 over against.If the controller 6 of self-traveling scavenging machine 1 detects contact terminal 14 and switches on the charging terminal 205 of charging device 200 1 sides, then stop the walking of scavenging machine 1.
Charging device controller 250 detects the electric current that flows to charging terminal 205, judges that self-traveling scavenging machine 1 engages with charging device 200.Controller 250 makes charging device control of dust fan 206 carry out work at the fixed time, from the disposal box 21 of self-traveling scavenging machine 1 dust is attracted to charging device disposal box 207.Continue at the fixed time to attract.
After the attraction of judging dust finishes, if judging battery 22, the controller of charging device controller 250 or self-traveling scavenging machine 16 finishes charging, the self-traveling scavenging machine is retreated.And, make the charging terminal 208 of charging device 200 1 sides and charging terminal 14 disengagings of self-traveling scavenging machine one side.Perhaps, controller 6 or charging device controller 250 with self-traveling scavenging machine 1 stop on the battery 22 and add voltage.Because charging and dust discharge both are through with, so begin again when needing by the time to clean.
If according to present embodiment, then because will move to the disposal box 207 of charging device 200 1 sides by the dust in the discarded disposal box 21 of staff so far, so can reduce the capacity that needs the disposal box 21 of jumbo scavenging machine 1 one sides for the cleaning of restraining oneself.Therefore, can make the scavenging machine miniaturization.In addition, in the above-described embodiments, use the filter dirt separation, but also can be with the centrifugation mode of using in the electric cleaner.
And for example fruit even if then do not carry jumbo battery and disposal box, also can carry out large tracts of land or cleaning for a long time according to present embodiment.Because with the guide rail of physics, so can realize high automatic charging and the dust-exbaust system of certainty by enough simple structures.
Fig. 9 represents other embodiments of the invention.In the above-described embodiments disposal box is configured in the bottom of scavenging machine, but in the present embodiment, disposal box is configured in the top of scavenging machine.Therefore, it is also different with the foregoing description to be arranged on the dust-collection element of charging device one side.Fig. 9 represents scavenging machine 1a is contained in state among the charging device 200a, and Fig. 9 (a) is its top figure, and Fig. 9 (b) is its side cross-sectional views.
By the disposal box 21a that is arranged on the disposal box retainer 73 maintenance scavenging machine 1a on the face shield 27b.Check valve 77 is set on disposal box 21a, and around check valve 77, recessed cone shape bayonet socket 76 is seen in formation from the outside.The material of bayonet socket 76 is strong magnetic materials of iron etc.The top material of disposal box 21a all is a transparent resin except bayonet socket 76 and check valve 77.
Section port body 30 is same as the previously described embodiments, can change the position at left and right directions.The conduit 78 that stretches at above-below direction is connected with disposal box 21a with section port body 30.In the upper end of conduit 78 sliding panel 74 is installed.Sliding panel 74 can slide on the liner 75 that is installed on the disposal box retainer 73.The guide rail 63 that will be installed in the bottom surface of disposal box 21 in the above-described embodiments is installed on the bottom surface of scavenging machine 1A.But, do not need to be configured in the baffle plate 59 and the dust-exhausting port 60 of guide rail 63 peripheries in the present embodiment.
In the present embodiment, the formation of charging device 200a is also same as the previously described embodiments, but has only plate portion 202a different with the foregoing description with cassette portion 203a.Cassette portion 203a is positioned at the top of plate portion 202a, in scavenging machine 1a and state that charging device 200a engages, is in half the position, roughly front side that only covers scavenging machine 1a.Stretch out flexible flexible pipe 220 from charging device control of dust fan 206, flexible pipe 220 attracts dust.
Front end at flexible pipe 220 is installed with electromagnet 221, and charging device controller 250 can be controlled electric current.When the front end with flexible pipe 220 is drawn out to the outside of cassette portion 203a, when the determining positions of scavenging machine 1a is on charge position, bayonet socket 76 be positioned at flexible pipe 220 front end directly below.The leader 204 of charging device 200a is same as the previously described embodiments.
Below we illustrate the work of the present embodiment of such formation.Engage all same as the previously described embodiments with charging device 200a up to scavenging machine 1a.When charging device 200a engaged with scavenging machine 1a, scavenging machine 1a stopped walking.The charging terminal 14 that charging device 200a detects scavenging machine 1a one side contacts with the charging terminal 205 of charging device, begins charging.
250 beginnings of charging device controller are to electromagnet 221 energisings of the front end of flexible pipe 220.Make electromagnet 221 magnetization, and the bayonet socket (mouthful gold) 76 of kicker magnet between acting on gravitation.Flexible flexible pipe 220 stretches, and the front end and the bayonet socket 76 of flexible pipe 220 combined.So at this moment because electromagnet 221 and bayonet socket 76 become the structure that may close by circular cone intimate engagement positively.
Make 206 work of charging device control of dust fan, open check valve 77 with the pressure that generates.Dust in the disposal box 21a is attracted to charging device disposal box 207.If make 206 work of charging device control of dust fan at the fixed time, then stop to the energising of electromagnet 221.Because the elasticity of flexible pipe 220, the front end of flexible pipe 220 breaks away from bayonet socket 76.Therefore, finish to discharge dust from disposal box 21.Later work is all same as the previously described embodiments.
If according to present embodiment, then, enter in the charging device 200a from charging device 200a side so can prevent scavenging machine 1 because sidewall sections 202a is arranged on the both sides of charging device 200a.Because disposal box 21 is arranged on above the main body, be transparent resin system, so by the visual dust amount that can confirm in the disposal box 21.Can prevent mistake and inhale the state of affairs that valuables abandon with dust again.Make vertically high structure of cassette portion 203a because have, so can reduce the floor area that charging device 200a occupies.Because cassette portion 203a only covers the front side of scavenging machine 1a, so can expose the guidance panel 46 and the infra-red remote control receiving element 16 of the rear side that is configured in scavenging machine 1a.As a result, even if scavenging machine 1a is contained in the charging device 200a, also can easily operate and be far apart operation.
Figure 10 represents the variation of present embodiment.This Figure 10 is the side cross-sectional views of scavenging machine 1a and charging device 200c.Also same as the previously described embodiments in the present embodiment, cassette portion 203c is positioned at the top of plate portion 202c, and this point is different with the foregoing description but cassette portion 203c is positioned at all tops of plate portion 202c.
Be arranged on guidance panel 222 on the scavenging machine 1a and infra-red remote control receiving element 223 be arranged on charging device 200c above.The output of guidance panel 222 and infra-red remote control receiving element 223 is input to the controller 250 that is arranged on cassette portion 203c inside.Below cassette portion 203c, infra-red remote control transmitting element 224 is set.This transmitting element 224 is used to accept the instruction of self-controller 250 that remote signal is sent in the charging device 200c.On the top of the medial surface of the part of holding self-traveling scavenging machine 1, be provided with detect that self-traveling scavenging machine 1 enters charging device 200c enter detecting sensor 29, the output of this sensor is input to controller 250.
When on the push panel 222 during switch and in infrared ray remote control receiving element 223 receives from figure during the signal of unillustrated infra-red remote control transmitter, infra-red remote control transmitting element 224 sends to the signal of correspondence the remote control receiving element 16 of scavenging machine 1a.Therefore, even if scavenging machine 1a is contained in the charging device 200c, also can operate scavenging machine 1a.Again, because the upside of charging device 200c all becomes cassette portion 203c, so can make the further densification of charging device 200c.
Detect self-traveling scavenging machine 1a and enter charging device 200c if enter detecting sensor 229, then controller 250 sends instruction in order to send the signal that expression scavenging machine 1a enters charging device 200c from infra-red remote control transmitting element 224 to scavenging machine 1a.Therefore, enter charging device 200c with the other places even if scavenging machine 1a is predetermined in walking, also can be at scavenging machine 1a and the progress path that changes scavenging machine 1a before charging device 200c engages.
Again, do not work, do not enter charging device 200c, improve the speed of travel so can know scavenging machine 1a because when scavenging machine 1a does not enter the inside of charging device 200c, enter detecting sensor 229.As a result, when scavenging machine 1a engages with charging device 200c, before near charging device 200c, can both walk at a high speed, only near charging device 200c, reduce the speed of travel, can make scavenging machine move towards charging device 200c soon.As a result, because can improve the speed of travel before arriving charging device 200c, walking lentamente after arriving charging device 200c is so can improve sweeping efficiency and positively charge and dust discharge work.
In addition, if, then also can save and enter detecting sensor 229 in order not allow the signal that sends from infra-red remote control transmitting element 224 escape to the outside of charging device 200c and determine the position of infra-red remote control transmitting element 224 and the shape of plate portion 202.At this moment, preferably send the signal that expression always enters from infra-red remote control transmitting element 224.
If according to the present invention, then because can mobile section port body, the side cover can detect the barrier direction, so can clean each corner in room with restraining oneself.Because leader and dust component are arranged in the charging device,, can clean with self-traveling scavenging machine self-discipline ground so do not need just can charge and dust discharge with hand again.Meanwhile, can carry out long-time or large-area cleaning.Further, can make the miniaturization of self-traveling scavenging machine.
